Overview
The SN74AHC4066DBRG4 is a quadruple bilateral analog switch manufactured by Texas Instruments, belonging to the 74AHC logic family. It features four independent SPST switches in a 14-pin SSOP package. The device operates on a single supply voltage ranging from 2V to 5.5V. Key electrical specifications include an on-resistance of 75 ohms maximum at VCC=3.3V and 55 ohms at VCC=5V. Propagation delays are typically 12ns at 5V with 50pF load. The component supports a wide operating temperature range from -40°C to +85°C and complies with RoHS3 standards.
Feature Summary
- Provides four independent bilateral analog switches for signal routing
- Operates across a wide 2V to 5.5V single-supply voltage range
- Features low on-resistance for efficient signal transmission
- Compatible with CMOS and TTL logic output levels
Applications
- Data acquisition systems requiring signal multiplexing
- Battery-powered consumer electronics due to low voltage operation
- Industrial process control signal switching
- Communication equipment interface isolation
Procurement Notes
Verify the presence of the G4 suffix indicating lead-free and halogen-free compliance. Confirm the DBR package designation corresponds to the 14-SSOP form factor. Ensure the manufacturer identification matches Texas Instruments to avoid counterfeit components. Check datasheet revisions for any pinout or electrical parameter updates prior to integration.
Selection Notes
Select this component when multiple independent analog signal paths require switching within a compact surface-mount footprint. The 74AHC series offers faster switching speeds compared to standard HC logic while maintaining low power consumption. Consider the 75-ohm on-resistance limit for applications sensitive to signal attenuation. Verify that the required supply voltage falls within the 2V to 5.5V operational window.
Part Context
This part is a specific variant of the SN74AHC4066 series, distinguished by the DBR package code for SSOP housing and the G4 suffix for environmental compliance. It serves as a digital-controlled analog switch solution within Texas Instruments' high-speed CMOS logic portfolio. The device replaces older analog switching technologies with integrated digital control capabilities.
Replacement Considerations
SN74AHC4066DR: Identical function in SOIC-14 package. SN74AHC4066PW: Equivalent performance in TSSOP-14 package. CD74HC4066M: Higher speed but different logic family characteristics.
